Okay, so a "problem upon initiation" does not occur.

This is _very_ strange. Do you have anything in your login
scripts, like ~/.cshrc (or ~/.tcshrc), ~/.login or ~/.profile
that looks "offending"?

I'm not sure what part of the system could trigger that behavuiour,

However, you could run truss on an login attempt to see what
the process does (invisibly), calling /bin/chmod via execve()
or by chmod() or popen().
